摘　　要：介绍了高压电网电气设备绝缘性能在线监测方案,提出了面向对象的在线监测电气设备及参数的单元设计方法。通过监测电容性设备介质损耗(tanδ)、氧化锌避雷器阻性电流、变压器铁心电流和变压器油中各气体的含量来判断电气设备的绝缘性能。On-line insulation monitoring schemes for high voltage grid electric equipment are discussed, and modular designs of object-oriented on-line monitoring electric equipment and their parameters are suggested. The insulation properties of electric equipment are judged by monitoring medium consumption (tan δ) of capacitance equipment, resistance current of zinc oxide lighting arrester, core current of transformer, and content of gas in transformer oil.
